33: The Animal Body: Basic Form and Function
Vibrio Cholerae: Causer of Cholera (Microscope Image) What is Cholera is a disease caused by a microorganism named Vibrio cholerae, the choleric vibrium is a bacterium that has the ability to multiply at a rapid rate within the human gut. Knowing the disease this bacterium causes strong fermentation reactions in the digestive system and releases a potent toxin "triggering" of severe diarrhea.
Mouse: Main Disease Transmitter What is Leptospirosis Leptospirosis, also called Weil's disease, is a bacterial disease that affects humans and animals and, in its most severe condition, can lead to death. Important Information Classified since 1917, this zoonosis (zoonoses are diseases of animals transmissible to man as well as those transmitted from man to animals.
Mycobacterium leprae: Leprosy-causing bacteria (magnified image under microscope) Cause of the disease Leprosy (formerly known as leprosy) is a contagious infectious disease caused by a microorganism (bacteria) called Mycobacterium leprae. Transmission Transmission occurs through direct contact with untreated patients, as they eliminate the bacilli through the upper respiratory tract amid nasal secretions and droplets of speech, cough and sneeze.
Body Tinea: One of the Mycoses Caused by Fungi Introduction Many types of fungi that settle in the human body can cause disease. Most of these fungi look for hot and humid places in the body to develop. These fungi usually settle on the skin, scalp and nails. Main diseases caused by fungus - Tinea of the body: superficial mycosis of the skin, characterized by rounded spots with the presence of itching.
Polio Vaccination: Best Action Against Disease What is Polio, also known as Childhood Paralysis, is an infection that occurs through an RNA virus, known as poliovirus, which has three serotypes: I, II and III. Disease Information After settling in its host, the virus goes through an incubation period that can range from 2 to 30 days, but generally this period takes 7 to 12 days.
Rotavirus (microscope image) What is Rotavirus is an infectious disease caused by the virus of the genus rotavirus. It most severely affects children under the age of five. Symptoms Its main symptoms are severe diarrhea, vomiting and high fever. In adults such symptoms may present more mildly.
Air Pollution: Breathing Problems Introduction Since the mid-18th century, with the onset of the Industrial Revolution in England, air pollution has grown significantly. The burning of coal (energy source for the machines of the time) threw tons of pollutants into the atmosphere of industrial cities in Europe.
Ecology: living beings, the environment, and their relationships What Ecology studies Ecology is a science that focuses on the study of the multiple relationships that exist between living things, and those that exist between them and the environments of planet Earth. Importance With the significant increase in population over the last two centuries, as well as the advent of industrialization and intensification of urbanization, this science is of fundamental importance to understand the impacts caused by man on the environment.

Urban Ecology: important for the sustainability of the planet What it is - definition Urban ecology is a field of ecology whose object of study is the relations between the inhabitants of an urban area and their interactions with the environment. That is, it studies how plants, animals and people interact in a given urban environment (city, for example).
Atlantic Forest: a biome with rich biodiversity Location, general characteristics and data Atlantic Forest is an important Brazilian biome. It is a tropical forest, distributed in thousands of fragments from the coastal region of Rio Grande do Norte to Rio Grande do Sul. The Atlantic Forest is composed of a large group of forests.
Lion: Example of a Predatory Animal Predation and Predatory Animals (which they are) Predation, also known as predatism, is an ecological relationship in which an animal (predator) hunts, kills, and feeds on another animal (prey) of a different species. Most predatory animals are carnivorous (meat-eating) or omnivorous (meat-eating).
Greenhouse Effect: Harmful Effects on the World Climate What it is - definition The climate phenomenon known as the greenhouse effect has contributed to the rise in temperature on the globe in recent decades. Recent survey data show that the twentieth century was the warmest in the last 500 years. Summary of the main causes and consequences (effects) World climate researchers say that, in the very near future, rising temperatures from the greenhouse effect could favor melting of ice from the polar ice caps and rising sea levels.
Aquatic Ecosystems: Diversity of Life Introduction - Definition Aquatic ecosystems are those that have a body of water as a biotope, such as seas, rivers, oceans, lakes, marshes, etc. The best known types of aquatic ecosystems are: freshwater ecosystem and marine ecosystem.
Agaricus Campestris: fungus used in cooking Thousands of species - Currently around 73,000 species of fungi are known. However, fungal experts believe there may be about 1.4 million fungal species. World's Largest Fungus - In the year 2000, researchers found in a US forest the largest fungus of all time.
Virus-infected beanstalk What they are - biological definition Plant viruses are microscopic infectious agents that affect plants and can cause plant viruses. These viruses parasitize plants, multiply and can cause them to die. These viruses are highly harmful to agriculture as they cause damage by killing plants or making the fruits unfit for consumption.
Ecology: Three major branches of study Introduction The study of ecology can be divided into several branches (areas). The three main branches of this science are: Autoecology, Synecology and Demoecology. The division of ecology into these three major branches of study was made by botanist Carl Schroter in the early twentieth century.
Fungi: Absence of chlorophyll is one of the characteristics. General characteristics presented by the fungi: - They develop mainly in places with high presence of organic material and humidity. The lack of light also facilitates fungal development. - Can be multicellular (composed of more than one cell) or unicellular (composed of only one cell).
Amoeba, one of the best known parasites What they are Parasites are living things that draw from other organisms the resources necessary for their survival. Information on parasites (main characteristics) They are considered aggressors because they harm the host organism through parasitism.
